We are using Liferay Portal Community Edition 6.2.0 CE GA1 with no chance to update (guy responsible for that just don't want to do it), so i needed to make workaround for this.
Bug LPS-42075 is marked as fixed, but after i studied source codes i think, it's not really fixed. That changes can work only with locale.prepend.friendly.url.style=3 in your portal-ext.properties.
So i make own workaround for two our languages, but this time it works with locale.prepend.friendly.url.style=0
This is code form action mapping (we are using spring portlet mvc):
HttpServletRequest request = PortalUtil.getHttpServletRequest(actionRequest);
HttpServletResponse response = PortalUtil.getHttpServletResponse(actionResponse);
HttpSession session = request.getSession();
//portlet parameters, language is new language, refresh is url for redirect
String languageId = actionRequest.getParameter("language");
String refresh = actionRequest.getParameter("refresh");
if (!"sk_SK".equals(languageId) && !"en_US".equals(languageId)) languageId = "sk_SK";
Locale locale = LocaleUtil.fromLanguageId(languageId);
try {
ThemeDisplay themeDisplay = (ThemeDisplay) actionRequest.getAttribute(WebKeys.THEME_DISPLAY);
//this is from LR source code
boolean persistState = ParamUtil.getBoolean(request, "persistState", true);
if (themeDisplay.isSignedIn() && (persistState)) {
//user is logged, so we need to change his language and set session Locale
User user = themeDisplay.getUser();
user.setLanguageId(languageId);
UserLocalServiceUtil.updateUser(user);
session.setAttribute(org.apache.struts.Globals.LOCALE_KEY, locale);
} else {
//guest here, session locale is messing things, so remove it
session.removeAttribute(org.apache.struts.Globals.LOCALE_KEY);
}
//guest language cookie, should be set in both situations
LanguageUtil.updateCookie(request, response, locale);
} catch (SystemException ex) {
logger.error("FATAL",ex);
//TODO ignore?
}
//changes are applied after refresh, so we need to redirect to same url
try {
URL url = new URL(refresh);
response.sendRedirect(refresh);
} catch (MalformedURLException mue){
logger.warn("Malformed refresh: "+refresh, mue);
//TODO ignore?
}
}
And this is part od header jsp
<portlet:renderurl var="refresh" escapeXml="false" />
<portlet:actionurl var="setSkSk" escapexml="false">
<portlet:param name="action" value="changeLanguage" />
<portlet:param name="language" value="sk_SK" />
<portlet:param name="refresh" value="<%= renderResponse.encodeURL(refresh)%>" />
</portlet:actionurl>
<portlet:actionurl var="setEnUs" escapexml="false">
<portlet:param name="action" value="changeLanguage" />
<portlet:param name="language" value="en_US" />
<portlet:param name="refresh" value="<%= renderResponse.encodeURL(refresh)%>" />
</portlet:actionurl>
<a href="<%= renderResponse.encodeURL(setSkSk)%>">SK</a>
<a href="<%= renderResponse.encodeURL(setEnUs)%>">EN</a>
